Unknown Future's combat system is practically identical to that of Slay the Spire. Each player has three action points per turn that they can use to play cards. Each card usually costs between one and three action points. This game has attack, defense, and support cards, and you'll have to learn how to use them strategically to defeat all the enemies while taking as little damage as possible.
Win a battle, and you'll be able to choose from three different cards as a reward. Thus, as you fight battles, you can gradually create a custom deck of cards, and balance the number of attacks, defense, and support cards. Unknown future also lets you delete cards from your deck, so you can remove weak cards that only get in the way. Because, of course, the goal is to build the strongest deck possible!
Unknown Future is an exciting rouguelike with deep and entertaining gameplay, fantastic graphics, and unique maps. It's yet another great title from Netease, and successfully brings Slay the Spire's premise to the mobile device.
